Abstract (en)
[origin: EP3690532A1] Embodiments of this application disclose a backlight module, including a substrate, a plurality of spot light sources, an optical conversion layer, and a light mixing member. The plurality of spot light sources are fastened onto the substrate in a mutually spaced manner. The optical conversion layer is stacked on the substrate and covers the plurality of spot light sources. The optical conversion layer is configured to convert, into a white surface light source, light emitted by the plurality of spot light sources. The light mixing member is located on a surface of the optical conversion layer or embedded into the optical conversion layer. The light mixing member is configured to mix the light. The backlight module emits light evenly and has a relatively small thickness. The embodiments of this application further disclose a display screen and a terminal.
